What Does “Arm’s Length” Mean in Business?

If you run a small business in Australia, you’ll hear the phrase “arm’s length” pop up in contracts, funding rounds, tax conversations and board approvals.

It sounds technical, but the idea is simple and incredibly important: are you doing a deal on normal commercial terms, as if the parties were strangers, without special treatment?

Getting this right protects your cashflow, reputation and decision-making. It also helps directors meet their legal duties and reduces the risk of tax and shareholder disputes.

In this guide, we unpack the arm’s length meaning in plain English, walk through common scenarios for small businesses, and share practical steps to document and prove your deals are genuinely at arm’s length.

What Does Arm’s Length Mean (In Plain English)?

An arm’s length transaction is one negotiated by independent parties, each acting in their own best interests, without pressure, influence or special advantage from the other.

Put another way: would a reasonable outsider agree to the same price and conditions? If yes, you’re likely at arm’s length. If your decision is swayed by friendship, family ties, ownership links or personal benefit, it’s not.

Key features of arm’s length dealings include:

• Independent decision-making: no party controls or improperly influences the other.
• Market-based terms: price and conditions align with what comparable businesses would accept.
• Clear documentation: written contracts, approvals and records that reflect a genuine negotiation.
• Fair process: conflicts are disclosed and managed, and those with a personal interest don’t rubber-stamp the deal.

Why does this matter? Because many small businesses trade with related parties-think director loans, leasing a property you own to your company, or buying services from a founder’s other business. These arrangements can be legitimate and helpful, but only if handled at arm’s length.

Why Arm’s Length Dealings Matter For Small Businesses

Arm’s length isn’t just a best-practice buzzword. It supports compliance, governance and commercial outcomes in several ways.

1) Protects Directors And Decision-Makers

Directors must act in the best interests of the company. Approving related party deals at market terms-and documenting how you reached that view-helps demonstrate sound decision-making. Processes that encourage informed, independent judgment also align with the business judgment rule under section 180(2) of the Corporations Act, which you can explore in our guide to the business judgment rule.

2) Reduces Disputes Between Founders And Investors

If one founder leases equipment to the company at a premium, or pays themselves back a “loan” on unusual terms, you can expect friction. Arm’s length policies make expectations clear and provide a fair yardstick if disagreements arise. A tailored Shareholders Agreement often sets boundaries for these situations.

3) Supports Tax And Accounting Integrity

Accountants and the ATO will expect related party arrangements to reflect market value. When transactions are on ordinary commercial terms-and you’ve got evidence to back it up-it’s easier to defend your position. For example, if a director lends money to the company, documenting interest, security and repayment terms in a proper Loan Agreement is a smart baseline.

4) Builds Trust With Customers, Staff And Partners

Transparent, consistent decision-making builds confidence. Suppliers are more willing to extend credit, staff feel the business is run fairly, and potential investors see a well-governed operation rather than an owner-managed “black box.”

Common Situations Where Arm’s Length Rules Apply

Here are everyday scenarios where small businesses should pause and check for arm’s length risk.

Director Or Shareholder Loans

Many startups are funded by founders’ personal loans. That’s common-and fine-if agreed on fair terms. The ATO and auditors expect an interest rate, security (if any), repayment schedule and default consequences that look like a normal commercial loan. Our explainer on director loans covers the key considerations.

If the loan is secured, consider registering the security on the PPSR and using a General Security Agreement. Getting the security perfected and ensuring priority sometimes involves separate steps, such as arranging to register a security interest.

Leasing Property You Own To Your Company

If you (or a related entity) own premises and your company is the tenant, set rent and outgoings at market value, and use a proper commercial lease. Benchmark against comparable local properties, document rent review mechanics and avoid informal “mates’ rates.”

Intercompany Services And IP Licensing

If you operate a group (for example, a holding company that owns IP and a trading company that uses it), fees should be supported by a services or licence agreement. Fees need to reflect market value and the substance of what’s provided. Where you’re licensing IP owned by one entity to another, make sure the scope and price are clearly set out in a written agreement.

Buying Or Selling Assets With Related Parties

From equipment to domain names, asset transfers within a founder group should use a sensible valuation approach, a written sale contract and standard conditions like delivery, warranties and risk transfer. If you’re unsure, an independent valuation or at least multiple quotes can help-especially for harder-to-price assets like private company shares, where a framework like those discussed in valuing shares in a private company can guide you.

Guarantees And Related Party Support

It’s common for founders to personally guarantee a company’s lease or finance. Make sure guarantees are documented and understood. If the company seeks support from related entities, consider formalising it with a Deed of Guarantee and Indemnity, and ensure the terms aren’t more onerous than a third party would accept. Our overview of personal guarantees explains the risks.

How Do You Prove A Deal Is At Arm’s Length?

Arm’s length is about both substance and evidence. You need to actually negotiate fair terms-and be able to show how you reached them. Here’s a practical playbook.

1) Identify And Disclose Conflicts Early

Start by asking: does anyone involved stand to benefit personally from this deal? If yes, disclose it to decision-makers in writing. In meetings, the interested person should withdraw from voting. A simple policy makes this repeatable; many SMEs adopt a concise Conflict of Interest Policy so there’s no ambiguity.

2) Benchmark The Price And Terms

Gather evidence a third party would accept the same deal:

• Obtain two or three independent quotes for comparable goods or services.
• Research publicly available market rates (e.g. commercial rent per square metre in your suburb).
• Use an independent valuation for significant or unique assets.
• Check standard clauses in similar contracts to ensure your terms are not unusual.

Keep your notes, emails and quotes. If challenged, this file becomes your “audit trail.”

3) Use Proper Contracts And Execution

Document the deal in a written agreement that covers key commercial terms, termination, default and dispute resolution. Make sure the company executes contracts correctly-our breakdown of section 126 of the Corporations Act explains how companies can authorise people to sign on their behalf. If director signatures are used, ensure they’re the appropriate signatories and any conflicted director steps back as required by your governance documents.

4) Record Approvals And Rationale

Board or management minutes should set out the nature of any conflict, who abstained, the market data reviewed, and why the terms are considered fair. This kind of record supports informed decision-making and sits well with the principles of the business judgment rule discussed above.

5) Review Regularly

Long-term related party arrangements-like leases or service agreements-can drift away from market value over time. Build in periodic reviews and, where appropriate, rent or fee adjustments tied to a benchmark (e.g. CPI or market rent reviews).

6) Separate Personal And Company Money

Avoid informal transfers. If the company owes a founder money, document it. If a founder incurs costs, reimburse via normal expense processes. Where funds are advanced, treat them as a documented loan on commercial terms rather than an undocumented “float.”

What Contracts And Policies Help You Stay Arm’s Length?

The right contracts and governance documents make “arm’s length” your default setting. Consider these core tools.

• Shareholders Agreement: Sets rules for related party transactions, approvals for major decisions, dispute resolution and exit mechanics. A clear Shareholders Agreement reduces grey areas and keeps founders aligned.
• Company Constitution: Your constitution can address director conflicts, voting and execution. If you’ve never reviewed it, now’s the time to ensure your Company Constitution matches how you actually operate.
• Conflict Of Interest Policy: A short policy that requires disclosure and abstention when a personal interest exists. It’s particularly helpful as you grow and add managers or advisors. See Conflict of Interest Policy.
• Loan Agreement: If directors or related entities lend money to the business (or vice versa), use a written Loan Agreement with interest, repayment terms, and security (if applicable). Consider whether to register any security interest.
• Service Agreement Or Licence: For intercompany services or IP licences, use a tailored Service Agreement (or licence agreement) that outlines scope, fees, performance standards and termination.
• Deed Of Guarantee And Indemnity: Where founders give personal support, ensure a clear scope and fair limits using a Deed of Guarantee and Indemnity.

These documents don’t eliminate judgment calls, but they create structure, clarity and a paper trail that demonstrates good governance.

Arm’s Length In Practice: Simple Examples

Let’s make it concrete with two quick scenarios.

Example 1: Founder Lends The Company $50,000

You agree a fixed interest rate aligned with current business lending rates, monthly interest payments, an 18-month term and optional early repayment without penalty.

You sign a Loan Agreement, and the board minutes record that the loan was compared with two bank term sheets and is on competitive terms. The interested director abstains from the approval vote.

Result: Clear, documented, defensible-and consistent with an arm’s length approach.

Example 2: Company Leases A Warehouse From A Director’s Trust

Before signing, you obtain a commercial agent’s rental appraisal and two comparable listings in the same area. You set annual market reviews, standard outgoings and a three-month bond. A standard lease is executed correctly by both entities.

The board minutes note the comparisons, confirm the rent is within market range, and record the conflicted director’s abstention.

Result: A related party deal on normal commercial terms, supported by evidence.

Governance Tips To Embed Arm’s Length Thinking

Arm’s length shouldn’t be a scramble every time a related party issue appears. Build it into your DNA with these habits.

• Use written policies and checklists so everyone knows the process when conflicts arise.
• Keep approvals and minutes short but specific: conflict disclosed, market checks done, decision basis noted.
• Refresh your market data annually for recurring arrangements (rent, service fees, licence fees).
• Train your leadership team to spot conflicts early and escalate promptly.
• Ensure signing authority is clear and compliant with company law-see our overview of section 126 for execution basics and delegated authority.
• Where deal complexity increases (e.g. large asset transfers, new investors), consider independent advice or valuation support-especially for share transfers or pricing decisions similar to those discussed in private company share valuation.

Frequently Asked Questions About Arm’s Length

Is a related party deal automatically non-arm’s length?

No. A related party deal can be arm’s length if it’s on market terms and approved via a fair process. The relationship simply means you should be extra careful with disclosure, benchmarking and documentation.

Do I need independent valuations every time?

Not always. For small, routine transactions, multiple quotes and good file notes can be enough. Use independent valuations for significant or unusual assets, or where there’s no obvious market benchmark.

Can I charge 0% interest on a founder loan?

It’s generally better to put loans on commercial terms. Zero-interest loans can raise tax and governance questions. If you intend concessional terms, document the rationale and understand potential consequences before proceeding-our guide to director loans is a helpful starting point.

What if a lender asks me for a personal guarantee?

Personal guarantees are common. Understand the risks and consider their scope and limits. You can read about key issues in personal guarantees and formalise them via an appropriate deed if you proceed.
